7A -C/D Win 09 Quiz 4 DL Sec Last 6 digits ID # Name (Last, First) Grade 1) The potential energy between two particles as a function of separation is graphed to the right. Starting from a temperature of zero Kelvin, we add a total of 10 x 10 -21 J energy. Describe the behavior of the system after we wait some time. Include an explanation as to whether the two atoms are bound or not . Ignore interactions with any other particles. 2) This time, we give the two particles a fixed total energy of -4 x 10

Unformatted text preview: -21 J. a) Plot the KE on the graph above as accurately as you can. b) What are the maximum and minimum separations the two particles may have, or do they exist? Explain. c) Over some time, what are the average PE and the average KE for the particles? Explain. PE + KE = E Tot KE = (1/2)mv^2 |F| = |d(PE)/dr| = |slope| of PE vs. r graph Separation (10-10 m ) PE (10-21 J) 2-2 4-4...
